Sliotar

A sliotar (/ˈslɪtər, ˈʃlɪtər/ S(H)LIT-ər, Irish: [ˈʃl̠ʲɪt̪ˠəɾˠ]) or sliothar is a hard solid sphere slightly larger than a tennis ball, consisting of a cork core covered by two pieces of leather stitched together. Sometimes called a "hurling ball", it resembles a baseball with more pronounced stitching. It is used in the Gaelic games of hurling, camogie, rounders and shinty.
